[v3,0/3] drm/connector: Provide generic support for underscan

Message

Hello,

This is an attempt at providing generic support for underscan connector
props. We already have 3 drivers defining the same underscan, underscan
vborder and underscan hborder properties (amd, radeon and nouveau) and
I am about to add a new one, hence my proposal to put the prop parsing
code in the core and add ->underscan fields to drm_connector_state.

This v3 was based on the "VC4 cursor scaling" changes, and thus address
Ville's concern about cursor plane not being rescaled with the other
ones.

Note that I dropped the nouveau conversion. I'll post a new version
once/if the generic stuff are accepted.

Regards,

Boris
